2016 article

A Network Approach of Gene Co-expression in the Zea mays/Aspergillus flavus Pathosystem to Map Host/Pathogen Interaction Pathways

Musungu, B. M., Bhatnagar, D., Brown, R. L., Payne, G. A., OBrian, G., Fakhoury, A. M., & Geisler, M. (2016, November 21). Frontiers in Genetics.

By: B. Musungu *, D. Bhatnagar*, R. Brown *, G. Payne n, G. OBrian n, A. Fakhoury*, M. Geisler *

author keywords: Aspergillus flavus; Zea mays; networks; RNA-sequencing; gene co-expression analysis
topics (OpenAlex): Plant-Microbe Interactions and Immunity; Plant pathogens and resistance mechanisms; Fungal and yeast genetics research
TL;DR: A gene co-expression network (GEN) was generated using a dual RNA-seq study with the fungal pathogen Aspergillus flavus and its plant host Zea mays during the initial 3 days of infection to reveal a high degree of connectivity in many of the previously recognized pathways in Z. mays.

MeSH headings : Antifungal Agents / pharmacology; Aspergillus flavus / genetics; Blotting, Southern; Drug Resistance, Fungal / genetics; Genes, Fungal; Genetic Complementation Test; Mutagenesis; Mutagenesis, Insertional; Orotic Acid / analogs & derivatives; Orotic Acid / metabolism; Phleomycins / pharmacology; Polymerase Chain Reaction / methods; Protoplasts; Spores, Fungal / genetics; Transformation, Genetic; Uracil / biosynthesis
topics (OpenAlex): Mycotoxins in Agriculture and Food; Fungal and yeast genetics research; Plant Pathogens and Fungal Diseases
TL;DR: The phleomycin resistance as a new positive selectable marker for genetic transformation of A. flavus allows strains to be transformed without having to generate an auxotrophic mutation, which is time consuming and may result in undesirable mutations. (via Semantic Scholar)
